Be it known that I, OSCAR A. GILBERT, a citizen of the United States,residing at Floyd, in the county offDane andl State of Wisconsin, haveinventeda new and useful Spring- Motor, oi-whif-,h the following is aspecifica-` tion.

This invention relates to spring-motors,and hasfor one object to providean improved device of this character for supplying power for any desiredpurpose.""" `lt is furthermore designed to provide an improvedarrangement of governor and brake devices which are applied to they-wheel of the motor in a`posi tion for convenientadjustment to controlthe speed of the motor, and, nally, to provide an adjustable windingdevice which may be thrown out of operative connection with-the motor,so as to remain inactiveduringthe operation of the latter.

with these-and other objects in viewtht4 present invention Consists inthe combination after more fullydescribed, shownfin the accompanyingdrawings, and particularly point-'- ed out in the appended claims, itbeing understood that changes in the form, proper-- tion, size, andminor details may be made within the scope'of thel -clai'ms withoutdeparting from the spirit oI"sacI'iflcingv any of the advantages of theinvention.-

In 'the drawings, Figure l' is a Side 'eleva tion of a spring-motorconstructed in accordance with the presen-tinvention.4 Fig. 2 is anenlarged transverse sectional view there of. Fig. 3 is a detail planview pf the winding device. l v

Corresponding parts in the several figures of the drawings aredesignated by like charactors of reference.

l In carrying out the present invention I provide a frame comprisinguprights or cornerposts 1 and the cross-bars 2, connectingthe 'uprightsand completing the frame for supwith the ily-Wheel 4. and thefdrive--wheel- 5,; which:` latter mayberprovided with a wrs'tnpin connectingrod, or it. may be a sprocket wheel for drivinga sprocket chain or belt,as maybe desired or convenient. The lfly-wheel `4 is mounted to turnloosely upon the shaft in a direction opposite to that of the hands of aClock,-as indicatedby the arrow in Fig. l of the drawings, and is lockedwiththe shaft for motion in the opposite direction' by means of aratchetpawl 4, carried by the outer end of the hub of the fly-wheel, andaixed ratchetwheel 3 upon the outer end of the shaft.

Located between the ily-wheeler mastergear 4 and the adjacent side ofthe supporting-frame is a coiled power-'spring 7, which has its oppositeends connectedto thefy- Vwheel and the fra-Ine of the'motoigrespectively. ,.This master-gear 4is provided with a peripheralseries of..ge'ar'teeth.8 to mesh with v the teethof a smallerwinding-gear 9, which ,isflocated-in rear ofthe master-gear and mountedupon' the frame. "of the'winding-goar is carried by a-,slidable Y andarrangement of parts, as will be herein-f. f'-

The stub-shaft lOl bearing'fplate 11, which is slotted longitudi nallyand provided with` fastenngs 12,'whichextend through `the -slottedVportions of the plate to slidably'secur'e the latter to the frame. Anysuitable4 operating crank or handle 13 vmay be removably'tted to theouter end of the stub-shaft, so as to provide means for convenientlywinding thepowe'r-spring upon the powershaft. It will be'understood thatthe bearing-plate 11 isadjustable toward andA away from the mastengear,so that the wind'- ing-gear may be brought into mesh with themaster-gear to Wind up the spring and also moved out of operativeconnection therewith.,

so as to remain inactive, when the motor is` in operation. A pawl 14:which is adjacent to the'master-gear and also ismounted upon theuprightV located below the latter, so as to engage the I toothedperiphery thereof. This pawl is normally held in engagement with themastergear by means of a weighted gravity-'deteut 15, which is pivotedintermediate of ltts ends to the adjacent upright, so that its upperlight end is in frictional engagement with the under side' of the pawland is designed Vto be disengaged therefrom by raising the weightedend-of thedetent, so'that the spring 16 may IOO ma@ the WW1 away fromitbmasterfgear dur.-

ing' the operation of the motor.

' sion 17, which projects a suitable distance master-gearoriy-wheel. Thegovernor-shaft .ceives said shank. It will of course be unpost, and isprovided at its lower end with a governing device comprising a fixedsleeve or The outer ends of these arms are provided with hollow casings25 to loosely contain the l'fixed s leeve by means of links 28, whichhave Vslidable sleeve 23 and i's'screw-threaded to ner of any ordinarygovernor. derstood-.that the governor acts merely in the The upright orend post which is adjacent to the master-gear is provided with anextenabove the master-gear, so as to carry an up-l right governor-shaft1S, which is mounted in suitable l'iearing-brackets 1,9,Y carried by thepinion 20, which is in mesh with a laterallydisposed series of marginalgear-teeth 21, provided upon the adjacent side of the mastergear andwhich project outwardly in planes substantially at right angles to thatof the extends above the upper end of the post or upright 17 and isprovided with a centrifugal collar 22, and a superposed movable sleeve23, which is slidable upon the governor-shaft and provided with a pairof diametrically opposite radial arms 24, which have their inner endspivotally connected to the slidable sleeve.

balls-26. Interposedbetween the opposite` sleeves, embracing the shaftand bearing in opposite directions against saidsleeves, is a coiledspring 27 to normally urge the slidable sleeve upwardly and away fromthe xed sleeve. The radial arms-are connected to the their opposite endspivoted to the sleeve and to intermediatel points of the arms,respectively. The upperextremityof the governorshaft extends above theupper limit of the receive a suitable nut 29, which is designed to forman adjustable stop for adjusting the limit of the movement of thesliding sleeve. By reason of `this arrangement the governor-4 shaft isoperated through the pinion 20, which is in mesh with the master-gear,-whereby the radial governor-arms are elevated 'by centrifugal forceagainst the tension of the spring 27 to govern the operation of themotor and insure a steady movement thereof'in the man- It will beuncapacity of a fly-wheel, as the arms 24 form fans to retard the motionof the motor-'Wheny it is first started, and when friction is sud``denly removed therefrom.

In order that the speed of the motor may" be controlled,therc isprovided a hook-shaped brake-arm or friction-clutch 30, which has ascre\ vthread ed shank or stem 3l, carried by a bracket 32, fixed to theupright 1,7. The upper end of the screw-threaded shank of the brake-armis provided with a suitable handle 33, whereby the shank may beturned tofeed the lattery longitudinally through the screwthreaded opening in thebracket which rederstood that the ybrake-arm has a swiveled connection34 with the shank, so that the same may turn independently of the latterwhen it is'desired to longitudinally adjust the device. As best shown inFig.` 2 of the drawings, the brake or clutch arm islocated at Vthe outerside of the master-gear, and lthe stopped, as'will be readilyunderstood.v It

willalso be observed that the brake and the governor-shaft arel inengagement with o'pposite sides of the (1y-wheel, so as to brace thelatter in opposite directions, and thereby prevent twisting of the wheelby the action of either the brake or the governor.

In the operation of the motor the windinggear is turned by means of thecrank or handle 13 in a direction to the right or to the movement-of thehands of a clock, thereby turning the master-gear in the oppositedirection to wind up the power-spring. It will .nowbe apparent that thepawl or ratchet device 14 is designed to prevent backward lrotation ofthe power-shaft and mastergear during the -winding` ofthe spring. Afterthe spring has been wound up the brake-arm 30 is adjusted so as to bindthe brake -shoe 35 Aagainst the Hange 36 of the -master-gear, so

as tohold the latter against turning, whereby the winding device may bedisengaged from the master-gear andthe pawl 14 maybe t rown out ofengagement therewith, when the motor is in readiness to be thrown intooperation by releasing the brake-shoe 35 from the master-gear.

It will now be understood that the fly-wheel is loosely mounted upon thepower-shaft, so as to turn to the left thereon in winding up the springwithout turning the shaft, while it is interlocked with the latter bymeans ,of the ratchet device to impart motion to said shaft when thefly-wheel is being turned-to theright under the influence of theunwinding-spring.

From the foregoing description it will be seen that the presentinvention provides an exceedingly simple and inexpensive device, inwhich the parts are'compactly assembled, so as to take up comparativelysmall space, arm the parts are in position forconvenient access, so thatthe motor maybe under complete control of the attendant. Moreover, thewinding device may be thrown outof operative connection with themaster-gear, so as to rid the motor of the unnecessary friction of suchwinding device when the motor is in operation.

What is claimed isl. In a motor, a spring-actuatcdpowershaft, afly-wheel carried thereby, a governor, having a shaft, which is inengagement with and driven byoneside of the fly-wheel, and

By this arrangement the y IOO a brake in frictional engagement with theopposite side of the wheel, the governor-shaft and the brake formingopposite braces for the Wheel, whereby the latter is prevented frombeing twisted by the action of either the brake or the governor-shaft.
